bipolar Hall switch Infineon TLE49681LHALA1 with wide voltage range and integrated protection features
Product Overview
The TLE4968-1L is a high-precision bipolar Hall effect switch designed for demanding automotive and industrial applications. It offers a wide operating supply voltage range (3.0 V to 32 V) with overvoltage capability up to 42 V without external resistors, reverse polarity protection, and integrated output overcurrent and overtemperature protection. Its key features include active error compensation for high stability of magnetic thresholds, low jitter, and high ESD performance. The TLE4968-1L is particularly suited for applications requiring high sensitivity and accurate switching near zero magnetic field, such as BLDC rotor position measurement and speed/position sensing in camshaft or transmission systems.
